No Multiplayer in some 2 Player Core GBA Games

[mister_fan]

Hello and thank you so much to everyone contributing to MiSTer

I wanted to report a weird issue with two games, and just with the GBA 2 player core.
These are The Lord of the Rings: The Two Towers and The Lord of the Rings: Return of the King (USA, Europe).

They load up fine but when attempting multiplayer, both games time out looking for other players. Resetting settings to stock, cold boot, neither fix it so it doesn't seem to be on my end? I don't have any other issues with multiplayer in any other games on the 2 player GBA core. The games are loaded from the GBA2P core games folder also. My GBA 2 player core version is 220813.

I know these aren't like priority games but they are IMHO fun little Diablo clones that would really benefit from local split screen.

Thank you everyone for working to preserve gaming history

GBAs have various ways to communicate with each other and most likely only 1 mode of them, which is covered by 90%+ of the games, is really supported currently.

Maybe this will improve in the future, but i cannot promise anything.

No worries Just saw no posts on this so had to make one.

Hey I just booted up LOTR Return of the King just for kicks and it works! You fixed it then? Was it just a problem with mine? Not sure but this is awesome, thanks either way!

I didn't fix anything recently, so maybe it was just random?

[mister_fan]

Yeah I really don't know? Gotta be me being stupid haha, sorry to waste your time

[mister_fan]

Ok I am sorry about this lol, but after an update all just now I have no more multiplayer in the above games, and I haven't changed anything except updating!

>_<

Is anyone else seeing similar behavior lol?

[FPGAzumSpass]

there was no update to the core in the last weeks since your post, so i guess it's just random?

If that helps you: i just tried "return of the king" with GBA2P from 22.08.13 and it works fine in multiplayer for the first few minutes i tested.

[mister_fan]

Yeah so I have the same GBA2P version and there's no change, can't see the other player when trying to link in ROTK and Two Towers....

My MiSTer is fine otherwise, I have no fancy hardware and my software is an update all clone; no custom scripts or anything. And Shining Soul 2 multiplayer works first time, every time, never have an issue with other games on GBA2P. I'm so confused hahaha

There's nothing I can do really and its not a huge deal for the community so I don't want to keep bugging everyone, thanks for all your hard work and assistance anyway
